Explanation
* addEventLister mousemove
Use the element.addEventListener() method to attach an event handler to a specified element.
onmousemove: Fires when the mouse pointer is moving while it is over an element
* The clientX property returns the horizontal coordinate (according to the client area) of the mouse pointer when a mouse event was triggered.
Example:
Output the coordinates of the mouse pointer when an mouse event has occurred:
var x = event.clientX; // Get the horizontal coordinate
var y = event.clientY; // Get the vertical coordinate
var coor = "X coords: " + x + ", Y coords: " + y;
The result of coor could be:
X coords: 142, Y coords: 99

Explanation
* The serialize() method creates a URL encoded text string by serializing form values.
You can select one or more form elements (like input and/or text area), or the form element itself.
The serialized values can be used in the URL query string when making an AJAX request.
Example: $("form").serialize());
* decodeURIComponent
The decodeURIComponent() function decodes a URI component.
Return Value:A String, representing the decoded URI
Incorrect:
Not decodeURI:
decodeURI is intended for use on the full URI.
decodeURIComponent is intended to be used on .. well .. URI components that is any part that lies between separators (; / ? : @ & = + $ , #).

Explanation
Box 1: var img = document.createElement('img');
Box 2: img:alt = image.Description;
img src = image.FileName;
Box 3: return this.img;
Note:
* Image Object
The Image object represents an embedded image.
For each <img> tag in an HTML document, an Image object is created.
Notice that images are not technically inserted into an HTML page, images are linked to HTML pages. The
<img> tag creates a holding space for the referenced image.
* Image Object Properties include
alt, Sets or returns the value of the alt attribute of an image
src, Sets or returns the value of the src attribute of an image
